. 1: m (cumn) The-invention relates to apparatus for and a duplicated is typewritten'or written in positive with hectograph ink on a plurality of strips of paper, eachof which strips, for example, maybe the record of the weekly payroll data for a certain individual. Along one edge of each strip, data is typewritten or. written giving the name of the individual and the amount the indlvidual'is to 16 receive for the-week. Other data, such as the number of hours or days of work for the week, mayv also be included. Each of these strips has a plurality of holes along one edge thereof so that the strips maybe assembled in overlapping :0 relationship upon a pegboard device with the matter to be duplicated appearing on the extending edge portions of the several strips, the pegs or pins oitheboard being muchsmaller in diameter than the holes in the strips. This difa ferential size of the openings facilitates the task oi distributing the strips upon the pegboard device in such manner that the data to be duplicated is left exposed. After the strips are mounted on the pegboard, they are aligned so go as to be brought into proper position with respect to each other by'pressure on the ends of the sheets along the assembly by means'of' an aligning member or bar, after which a clamp is employed to hold the stripsin their aligned con- 35 dition and the assembly is removed from the pegboard and applied face down to a gelatin pad so that the data to be duplicated appears in reverse upon the pad. A copy sheetmay then be applied to the pad for duplicating in positive on the one sheet all of the exposed-data appearing in hectograph ink on the several strips.

- It is another object of my invention to improve apparatus of this type and the method of duplicating in sundry details as hereinafter set forth.

45 The preferred means and methods by which I have accomplished my several objects are illustrated in the accompanying drawings, in which,

Fig. i is a perspective view of the preterred form of my improved structure for arranging a 50 plurality of master sheets in assembled relation to each other .for duplicating purposes.

posing a portion of a top face of each of said sheets. v

Fig.4 is a view similar to Fig. 3 but with the master sheets moved to their normal adjusted positions and with a ripping or clamping device -a mounted effectively in position on the adjusted sheets.

- Fig. 6 is a perspective view of the adjusted asl0 sembly-of sheets with the clamping device there-Y on, suchassembly being in inverted position with a plurality of round pegs secured in its top face in evenly spaced relation adjacent to one edge of the. board, the pegs being in aligned position side by side. As is, best shown in Figs. 2 and 5, the board it is provided with supporting members I! of any suitable type at its corners on its bottom face for supporting the board evenly upon a table or other level surface.

In Fig. 3, there are shown a plurality of master sheets I! each-in the form of a comparatively narrow strip preferably formed of paper, having a plurality of openings H in their end portions of considerably greater diametrical size than that of the pegs H. The openings ll are arranged in evenly spaced relation to each other across the ends of the master strips IS, the spacing bein'g v such that the strips are capable of being mounted 'quickly and easily upon the pegs or pins II, and

being capable oi having an edgewise shifting movement with respect to the board It when so mounted loosely upon the pegs.

In'the arrangement as shown in Fig. 3, the openings H are circular in shape, so that the side portions of the openings adjacent tothe edge oi the sheet are obliquely disposed. As a result of thisarrangement, when the sheets I! are pressed in any manner towardthe left in Fig. 3, the openings fare brought into centered position in one direction withrespect to the pegs and the sheets or strips are aligned accurately in parallel posi- Means is provided on my improved board II for pressing the sheets it toward the left in Fig. 3, such means comprising a bar I! which is hingedly mounted at its lower edge at i6 upon the-edge of the board.

I With a plurality of master strips ll mounted loosely in position upon the pegs Ii on the board II, as is clearly shown in I'is; 3,-a portion oi thetop iace of each of the strips is exposed to view; in the arrangement oi the strips as shown in Hg. SI 3 the upper edge portion of each of said strips is so exposed. The master strips ll are designed to have any desired data written in hectograph ink upon the top edge portion oi each of the strips so that the copy ink entries are exposed I. at the top face oi the assembly as shown in Pig. 3. when the desired number oi strips 13 has been placed in position upon the pegs II, the alignment bar I! is to be moved from the positionasshowninlig.2to thepositionasshown I in Fig. 5, for bringing such bar into engagement with the end portions of the strips for movirm them into adjusted parallel position as shown in Fig. 4, the spring ll being of such strength astobringthealignmentbarupsharplytoits 4 raised position.

After the strips are brought into alignment as shown in Fig. 4, a gripping or clamping device is is to be applied to the free end portions of the strips as shown in said Fig. 4. In the arrangement shown, I have employed a clamping device comprising a plate 20, and a clamping bar It movably mounted with respect to the piate 2!, such clamping bar II in the arrangement shown being provided with a pressure strip 22 preferably of rubber. The bar ii in the arrangement shown is carried by an arm which has a pivotal connection with the plate il, a spring 26 being provided'ior normally holding the pressure strip 2! in engagement with the top iace oi u the plate 2|. In-the arrangement shown, the

plate to is provided with a downwardlyextending flange II along one edge.

2. A method of duplicating subject matter from a plurality oi master sheets each having a plurality oi openings therethrough at one edge portion, which method comprises arranging the several sheets adjustably in overlapping relationship on a series of pins on a support so that a portion oi the duplicating face of each sheet is exposed, adjusting the sheets accurately with respect to each other on said support for duplicating purposes by preming them against said pins by manipulation oi the sheets from one side only of the assembly of sheets, clamping the sheets together in adjusted position on the support, then removing the clamped sheets from the support and apor, plying the assembly to a duplicating medium for transierring the subject matter in reverse irom the several sheets to said duplicating medium and then applying copy sheets to the duplicating medium for producing the composite subjeot'mat- 7o ter in positive on said copy sheets.
